They both represent neighboring swing states in the Senate. They are both fiscal conservatives with long careers in government. Finally, they were both elected to the Senate in 2010 and thus face their re-election battles this year.
You may believe that the disparity is the result of Donald Trump dragging down the ticket but that’s only half the answer. The other half concerns those that are being alienated by the GOP presidential nominee, namely whites with a college degree.

Ultimately, Sen. Toomey will have to target the college educated voters in PA’s Acela corridor in order to win his second term.
