There are mid-term elections in around 600 days in the USA..

Will these women get out and vote for all the boring, lower - level Senate, and House positions that come up at this time?

At present, there are more Democratic Senate seats that are opening than Republican, and preliminary polling says that the Republicans are on to a filibuster - proof 60 Senate seats, up from their current bare majority of 51-52 (not sure which).

Same with the House...

Will these women vote?

Usually Presidents lose Congressional seats (as did Obama) so far, it looks like Trump may break the trend and gain. If I am not mistaken the last time this happened was under FDR... Is Trump the new FDR? Laugh all you want, he is headed that way....

Don't march, get out there and register, and organize.

In 1990 the Republicans decided that demographics will increasingly be against them, so they decided to get the legislative branch of government on their side... and they have been "winning" ever since.
