re: House of Rep elections

I live in a competitive district that is getting a lot of attention. The Democrat incumbent was one of the surprise "blue wave" freshmen who defeated a Republican incumbent in a district Trump easily carried the previous cycle. The amount of money being poured into her campaign is obscene. Every single ad on TV is for her (and most of her ads are trying to portray her as a moderate who will work with Trump and Republicans when she is a dyed-in-the-wool liberal. . She's been desperately campaigning to hold her seat since the day she was sworn in.

Here is the recent District voting history:

2014: 148,000 Republican votes, 90,000 Democrat votes
2016: 218,000 Republican votes, 160,000 Democrat votes
2018: 176,000 Democrat votes, 170,000 Republican votes
