This nomination/confirmation is more important to the future of the Republic than a fleeting Senate majority.
Maybe the presidency itself.
A confirmed conservative justice could stop the dems from stealing the election.
The confirmation fight will probably have a significant impact on the election, including POTUS and the balance/control of both houses of congress. Outrageous behavior by the left during confirmation, along with more riots and "mostly peaceful" protests, might benefit some Republicans, but don't forget that we lost the House of Representatives right after the Kavanaugh fiasco. It could be a mixed bag.
