Electoral College: Bump? Bump? Is there a bump yet?

States with new poll data since the last update: Georgia, Ohio, Nevada, Michigan, Missouri, New Hampshire, Kansas.

The quick answer to the question in the subject of this post is “not yet”, at least in terms of what can be detected in state poll averages like we track here. Plenty has been written elsewhere on the Trump bump in national polling averages such as Pollster and RCP. There does appear to be a bump after the Republican convention. It takes a lot longer for these effects to show up at the state level, so we are unlikely to see individual effects for the two conventions. Instead we’ll see the net effect after both.

In the meantime, there are indeed two changes from the latest batch of polls, and they both are in Trump’s direction. In one case the data is from before the convention, and in the other the movement is small, so it isn’t enough to call out as a bump yet. Looking at them individually:

Michigan

chart-213

Even though one poll was just added, the most recent poll in Michigan is still from before the Republican convention, so we can’t read anything about a bump into it. But it did cause some polls that were very favorable to Clinton to roll off the poll average, so the average spikes up in Trump’s direction.

There haven’t been any polls actually showing Trump ahead in Michigan in almost a year, but with this Clinton’s lead drops to 4.8%, so we consider it a potential pickup for Trump.

Trump’s best case moves from winning by 40 electoral votes to winning by 72 electoral votes. To get there he still has to flip Nevada, New Hampshire, Iowa, Florida, Ohio, Pennsylvania, North Carolina and Michigan. Clinton is still ahead in all of those states, but by less than 5%. The “expected” result where everybody wins the states they are ahead in is still a 156 electoral vote victory for Clinton.

But Trump doesn’t need to flip ALL of those states to win, only some of them. How close is he really? That is where Ohio and the tipping point come in…

Ohio

New results from PPP, which ARE from after the Republican convention move the average from a 2.2% Clinton lead in Ohio to a 1.0% lead. Either way, the state is “Weak Clinton”, but because Ohio was the tipping point, this impacts the tipping point:

The tipping point moves from Clinton by 2.2% in Ohio to Clinton by 2.0% in Pennsylvania… so back to where it was right before the Republican National Convention started.

National View

Looking at the center part of spectrum of states… only those where the margin is under 10%, we now have this:

That is a lot of close or almost close states.

105.2 days until polls start to close on election day 2016.

Electoral College: Missouri out of reach for Clinton again

States with new poll data since the last update: New Hampshire, Alabama, Illinois, Alaska, Arkansas, Arizona, California, Colorado, Connecticut, DC, District of Columbia, Delaware, Florida, Georgia, Hawaii, Iowa, Idaho, Indiana, Kansas, Kentucky, Louisiana, Massachusetts, Maryland, Maine, Michigan, Minnesota, Missouri, Mississippi, Montana, North Carolina, North Dakota, Nebraska, New Jersey, New Mexico, Nevada, New York, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, Vermont, Washington, Wisconsin, West Virginia, Wyoming.

In addition to a handful of new polls, this batch of updates includes two sets of 50 states plus DC data from Morning Consult, one released in April covering January through March (with multiple candidate pairs), and another released in July covering April through June (covering only Clinton vs Trump). These span really long time periods and use a slightly different methodology than other polls, so I had initially not included them. But I was convinced by @hominidviews that I actually should include them, so they are now folded into the data.

In most cases, since the middates of the polling periods are fairly far in the past at this point, the addition of these polls only jiggled the lines around in the past rather than changing the situation as of today. Even in the sparsely polled states where these polls did change the average, categories did not generally change.

The one exception for Clinton vs Trump was Missouri:

Missouri

chart-211

With the new Morning Consult poll centered in May added, the July PPP poll was enough to end Missouri’s time as a close state that was caused by a March DFM poll that now looks like a pretty clear outlier. So Missouri moves from “Weak Trump” to “Strong Trump” and it is therefore no longer listed as a possible pickup for Clinton.

chart-212

Back in the past, you can see a few new features added by the Morning Consult polls… a dip in the expected line for a little while in May where Clinton briefly was in the lead in Georgia, and a spike in Clinton’s best case where she got within 5% in Texas… for one day.

The only change that hasn’t already come and gone is the change in Missouri. Clinton’s best case goes from winning by 230 electoral votes down to winning by 210.

Note this is not part of any “convention bump”. This change is due to poll information from before the convention. There should be new polls added soon that will tell us more about the impact of the conventions. This is not that.

Clinton vs Cruz

Oh, and the Morning Consult data had some Clinton vs Cruz information as well. Since that combination is still one of the five best polled combinations, even though Cruz lost, I’ll note the changes: Kentucky went from Strong Cruz to Weak Cruz, and Minnesota went from Strong Clinton to Weak Clinton. So Clinton’s best case moved from winning by 188 to winning by 204, and Cruz’s best case went from winning by 30 to winning by 50.
