Ms. Wilder has "grievances against the Republican Party" and won't vote for another Republican.  Her grievances:
1. Republicans have not declared war against ISIS.  Because Democrats can't agree on how broad the war powers should be.
2. By not holding hearings on the Supreme Court nominee, the Court is "hamstrung".  Hearings don't confirm Justices.  Since Scalia died, the Court decided 9 cases.  Three were decided 8-0.  One decided 7-1.  One decided 6-2.  One by 4-3 (Kagan recused).  Two ties but unlikely to have had a different result if Scalia were alive.
3. Delay of Loretta Lynch confirmation vote. Nominated January, 2015, hearings in January. A month to publish record. Two months to review record. Confirmed May 23, 2015. Not much delay.
4. Refused to consider gun control.  There were votes on 4 proposals in June.
5. State legislatures vote against LGBT and abortion.  Legislatures are different from the U.S. Senate; this is a reach. And Lisa is actually moderate on both issues.
