Anti-Trump Groups Think He Might Be 'Peaking'

Ted Cruz's relatively strong performance in Saturday's GOP contests has raised a host of questions about the Republican race going forward, much of them centering on Donald Trump. Some highlights:

• The New York Times details how anti-Trump groups are pouring millions into TV ads in key states amid "nascent signs that he may be peaking with voters."
• NBC News lays out why Trump's lead of 87 delegates is weaker than it appears.
• A post at Hot Air explains that a closer look at Saturday's results shows that Trump didn't under-perform at all; the key is that Cruz surged largely at the expense of Marco Rubio.

• One thing for sure: Trump is scrambling an Electoral College map that has been stable over the past four presidential elections. Politico digs in.
• On a similar note, the AP says that if Trump is the nominee, his path to a general election win "would be a GOP map unlike any in recent years." Think working class, white voters in traditionally blue states.
• Cruz says multiple media outlets have told him they've got big exposés ready on Trump, but don't plan to run them until June or July, reports Talking Points Memo.
• In the arena of Trump rivals, a Cruz super PAC is going after Rubio aggressively in the senator's home state of Florida, hoping to secure a potentially campaign-crippling defeat, reports Politico.
