Americans who have seen their paychecks grow thanks to the Trump-endorsed tax bill say they love it, though most of the country has yet to see results.

That's what respondents told pollsters conducting a new Politico/Morning Consult survey this month with support for the tax package remaining unchanged since January.

This week 45 per cent of voters said they supported the tax package – passed by the Republican majority in Congress in December – versus the 35 per cent who oppose it.

Voters who have seen a paycheck bump courtesy of the tax bill President Trump pushed are giving him and Republicans lawmakers credit, though only 25 per cent of survey respondents have seen those gains

In January, 45 per cent of respondents said they supported the tax bill, versus 34 per cent who didn't, indicating a change within the poll's 2 point margin of error.

In February a narrow majority of voters have yet to see a pay increase.

Fifty-one per cent say they haven't received a pay bump compared to the 25 per cent who indicated that they have.

That quarter of respondents, however, is heaping praise on President Trump and the GOP.

Forty-five per cent say they are now more inclined to support the tax bill because of that pay bump.

Thirty-seven per cent say they are much more likely to support President Trump, with another 21 per cent suggesting they were somewhat more likely to support the current commander-in-chief.

Overall that's 58 per cent who say their support of Trump increases as their paycheck grows.

On the flip side, 19 per cent of respondents said they would be less inclined to support Trump after their pay bump.

The poll suggests that Democrats may have trouble running against the tax package, though could be helped if the impact of the bill isn't widely felt.

Of those who saw pay spikes, 32 per cent said they'd be much more likely to support the GOP in Congress, while another 26 per cent said they'd be somewhat more likely to support Republicans, a bulk of whom are running for re-election in 2018.

Fifteen per cent said they would be much less likely or somewhat less likely to support Republicans now that they have a bigger paycheck.

Meanwhile, 30 per cent of the quarter of respondents who saw paycheck gains said they'd be much less likely to support Democrats, since the opposition party didn't support the tax bill.

Another 11 per cent said they'd be somewhat more likely to vote against the Democrats, who face a challenging Senate map come fall, and hope to retake the House of Representatives.
