"Democrats are openly encouraging millions of illegal aliens to break our laws, violate our sovereignty, overrun our borders and destroy our nation. In so many ways. We can’t let it happen."

This has been the constantly repeated message of the U.S. President Donald Trump during the last part of the campaign for the midterm elections, convinced that this is what will encourage voters to give their support to the Republican caucus on Tuesday.

However, the response of the voters is not monolithic, especially when all the seats of the House and only a few in the Senate are open for election.

According to Politico, the reaction of party members to the presidential campaign has varied according to the regions they represent and the demographics that can determine whether or not they continue in office.

"Senate Republicans seeking to grow their majorities in rural, red states by toppling incumbent Democrats have mostly welcomed Trump's red-meat approach," the media explained. "House Republicans whose survival hinges on the suburbs have privately griped and tried to change the subject."

An example of this was the presumed phone call of the Speaker of the House, Paul Ryan, to Trump on Sunday “for one final plea on behalf of anxious Republicans: Please, please talk up the booming economy in the final hours before Election Day,” added Politico.

These fears are not unfounded. According to the latest NBC/Wall Street Journal poll, "Democrats hold a seven-point advantage over Republicans," where 50 percent of potential voters have said they prefer a Democratic-controlled Congress, versus 43 percent who think otherwise.

Despite the recent news of a considerable increase in the country's workforce (250,000 new jobs according to the New York Times), and a historic minimum rate of unemployment (3.7 percent) - something that any candidate would have killed for during a campaign - Trump has decided to enclose himself in paranoid demagoguery against the Caravan of Refugees in Central America, the conspiracy theories about Democrats and undocumented immigrants and even the staging of a possible confrontation on the border between the U.S. military and the immigrant "invasion."

"Trump has hijacked the election," said one senior House Republican aide to Politico. "This is not what we expected the final weeks of the election to focus on.”
