The U.S. Republican Party has drawn two lines against the Senate election campaign:
The first line is called the “front line” and is the person most likely to lose his seat, including Maine Senator Collins, etc.;
The second line is called the “firewall” and is the people who are more likely to keep their seats, including Iowa Senator Ernest.
The U.S. Republican Party raised nearly $50 million in the first two weeks of October, hoping to ensure the competitiveness of U.S. Republican candidates in advertising.
In the 14 most competitive places in the United States, the Democratic candidate raised $84 million in the first two weeks of October, far higher than the Republican Party.
