All you folks who are wondering why Harris was so eager to work with the Cheneys and other Republicans and move further to the center, this is why. That 5% probably makes up a good portion of the difference between this poll and prior polls (along with the 6% of Republicans there who woudl vote for neither.)

This is exactly why Harris (and Biden before her) was careful to emphasize MAGA Republicans as threats to American democracy and not the Republican party as a whole, while the GOP desperately tried to paint that as an assault on every Republican. There is a nonzero number of Republican voters who can be persuaded to put ideology over party- the question is, is that number high enough to swing the election? So far, the answer looks like “yes”.
