My BIL, his Jewish wife and my “uncle in law” all say they don’t care if she were to get indicted. They are voting for her.
I believe most people who plan to vote for HRC still would vote for her if she should be indicted. However, if HRC is indicted for a felony, the Democrat Party is going to try to replace HRC because they know they'd be facing at least a year of Watergatesque hearings and trials if the nominee/incumbent/President were under federal indictment for a felony.
HRC is counting on the continued support of Dem voters, no matter what, and she'll probably have that. However, if you think the GOP establishment is opposed to its own front-runner, wait ‘til you see what happens on the Dem side if HRC is indicted. Biden and Elizabeth Waren will be trotted out pronto.
