One reason conservatives have been losing.
While the religious bunch are hoping God will do their work for them, God has given free will to everyone to find out what we will really do and how much we really care for the future of the USA.
As they "pray and fast" the democrats are out canvassing neighborhoods, handing out propaganda, registering voters and dragging the to the polls, and assisting them in absentee (or what they call "early voting").
God is looking down on the pathetic Christians and shaking his head at their laziness and inaction.
He has given them a brain, a body and a soul, which most choose not to use to their full capability, expecting God to step in and save their bacon from their own sloth.
If you don't want evil to win, get off your lazy behind and DO SOMETHING!
I hope you’re not proposing leaving the duty to God undone before acting. The most successful US presidents have been of the “religious bunch” and who have taught the people to do the same; the last of that bunch appears to have been Reagan, judging from his speeches.
