As President Donald Trump laid it out to reporters this summer, the plan was simple.
Republicans, the president said, were ''entitled'' to five more conservative-leaning U.S. House seats in Texas and additional ones in other red states. The president broke with more than a century of political tradition in directing the GOP to redraw those maps in the middle of the decade to avoid losing control of Congress in next year's midterms.
Four months later, Trump's audacious ask looks anything but simple. After a federal court panel struck down Republicans' new map in Texas on Tuesday, the entire exercise holds the potential to net Democrats more winnable seats in the House instead.
''Trump may have let the genie out of the bottle,'' said UCLA law professor Rick Hasen, ''but he may not get the wish he'd hoped for.''
Trump's plan is to bolster his party's narrow House margin to protect Republicans from losing control of the chamber in next year's elections. Normally, the president's party loses seats in the midterms. But his involvement in redistricting is instead becoming an illustration of the limits of presidential power.
Playing with fire
To hold Republicans' grip on power in Washington, Trump is relying on a complex political process.
Redrawing maps is a decentralized effort that involves navigating a tangle of legal rules. It also involves a tricky political calculus because the legislators who hold the power to draw maps often want to protect themselves, business interests or local communities more than ruthlessly help their party.
