It could be Democrat vs. Democrat in future Texas congressional district primaries if the state House of Representatives select committee on redistricting has its way.
The committee on Saturday released a new map that redraws those districts in clever ways -- for example, the Republicans who redrew the map merged two US congressional districts into one, both of them served by Democrats.
So if the map isn't changed, that new single district would see a standoff between two progressive Democrats: Longtime Representative Lloyd Doggett and Rep. Greg Caesar, who's 42 years younger than Doggett.
This would seem to leave Doggett with the possibility of retiring after more than 50 years as a Texas-based public servant (he's been a state Supreme Court justice and a state senator) or taking a chance on losing against Rep. Caesar.
Other districts will have some portions stripped out and replaced with other areas that could force changes in how Democrats campaign, including at least one district that will be less blue than it's been in the past as more conservative voters in a district would require a less progressive appeal for votes.
The committee's new maps are expected to go before the full state House in the coming week, as a special session that aims to address a number of issues continues, with less that three weeks to go.
