John Quincy Adams went from the US House the presidency, but that was different era and he was closely linked to the founding generation .

James Garfield was elected as the United States' 20th President in 1880, after nine terms in the U.S. House of Representatives.

Gerald Ford from my home state and city of Grand Rapids Michigan went from the US House after 25 years to being appointed VP for Nixon the n the presidentcyonce Nixon resigned. I don't know of any other US House members making the leap to POTUS.

15 senators later became president at some point. But as was pointed out, MTG would have to win a statewide election, not a gerrymandered single district. Georgia has two Democrats as senator. Both are closer to centrists politically, so it is unlikely a right wing nut like MTG can win that state.

Twenty presidents became so after having been, or were at the time, governors. Could MTG win the governor's seat in Georgia? About as likely as getting elected as a senator, IMO
