Mitt Romney hit his party’s “magic number” on Tuesday, unofficially clinching the Republican presidential nomination in a race he entered as the front-runner and has had to himself for weeks.

Romney led the pack when he announced his second run for the White House last June, and he has watched his rivals for the nomination slowly trickle out as their own wins looked increasingly unlikely.

The delegates to put him over the 1,144 necessary for the GOP nomination came in Texas, the lone state to vote this week. Romney entered the day 78 delegates away from the magic number, and on Tuesday CNN projected he would win the state’s GOP presidential primary, where 152 of the state’s 155 delegates were at stake.

On Tuesday, Romney said he was humbled to have secured the requisite delegates to become the GOP nominee.
