Romney was steadily gaining support from the beginning of September until early October, and he was in the lead in poll averages for about 10-14 days in October before his support started falling again.
I believe the current state of the electoral map certainly favors any Democratic candidate as has been discussed in this thread multiple times. As it stands today, Trump has to basically win every state that is currently a toss-up which includes Texas! A four-way race though, actually hurts Hillary the most AZ switches to Trump, NM, CO, and many other western states are much closer, etc. Now obviously all of that is within the margin of error, but ultimately the electoral map will favor the Ds at least until the next census.
Which just emphasizes the point. Romney was by far the better man. Polling data showed that the electorate over-whelmingly viewed him as more qualified to be President than Obama (more qualified than the sitting President!). They just didn't like his platform. Had he run on something approaching a Bush 2004 platform in regards to entitlements, he would easily have won.
But instead of moderating on Social Security a bit, we have to vote for the reality show clown to stop the Mexicans from destroying Western Civilization or something like that.
Romney's Social Security plan was really moderate - raise the retirement age by about two years and people making more than $450k/yr get lower SS benefits. Unless there was some part of the plan I was missing.
