Sixty-one percent of Republicans say they are satisfied with the direction of the U.S., according to a new Gallup poll.

It marks the highest level of Republican satisfaction since February 2007, according to Gallup.

Here are highlights from the poll:

Twenty-five percent of Republicans said they are "very satisfied" with the way things are going in the U.S., 36 percent are "somewhat satisfied," 23 percent are "somewhat dissatisfied" and 15 percent said they are "very dissatisfied."

Seven percent of independents are "very satisfied," 23 percent said they are "somewhat satisfied," 28 percent are "somewhat dissatisfied" and 38 percent said they are "very dissatisfied."

Less than .5 percent of Democrats said they are "very satisfied," 6 percent are "somewhat satisfied," 24 percent said they are "somewhat dissatisfied" and 68 percent are "very dissatisfied."

Gallup said Republicans' satisfaction comes after the GOP tax reform package was approved by Congress.

"Now that 2017 has been capped off with a major legislative victory and an improved economy, (President Donald) Trump's base is clearly pleased with what it is seeing from the GOP-controlled government," said Gallup's Justin McCarthy.

"As long as nothing reverses that momentum, Trump will be addressing a particularly energized Republican rank and file in his State of the Union address after a rocky year when they weren't so satisfied with the nation's direction."

The poll, conducted Jan. 2-7, sampled 1,024 adults. It has a margin of error of plus or minus 4 percentage points.
