Republican ideological divide plays out in Kentucky state legislature primaries
In the downballot races for the Kentucky legislature, Republicans aligned with the "liberty" wing of the party are taking on more establishment Republicans. Some of these conservatives are recent incumbents who won seats last cycle, while others are newcomers this year, but in general they take a harder line against government spending than what they call "establishment" Republicans.
Many in the liberty wing are endorsed by national PACs like Americans for Prosperity, and PACs backing "school choice" measures that would allow tax dollars to go to private schools. Battling over support for public schools has divided the party in other states, like Texas, and I've written about the universal school voucher movement's gains over the past two years.
Some swing state Republican Parties have also torn themselves apart over even the tiniest ideological differences in swing states around the country. Battles like those in Kentucky will help shape the general election to come, and could determine the direction the party takes in governing should it win big in November.
