"What would make for a good strategy?
How badly do you want to win?"
Go into the primaries with Conservative candidates and beat the snot out of their RINO opponents. Call the RINOS Democrats in Republican clothing. Don't give them any room to breathe.
Hammer it into the people, over and over that the reason this country went to crap over the last 6 years was because Republicans became Democrats and Democrats became Socialists.
Make the people choose between Socialism and Conservatism. Define it clearly and make the message concise.
That is how you take back this country.
Maybe.
