The reason is basic.
One, pretty much all conservative policies are bad for most people, so they have to lie in order to try and get votes from the people they are planning to harm.
Two, because enough people have figured that out, it's harder and harder for CONservatives to fool enough people into voting for them. That's why in the last seven US Presidential elections, the GOP candidate got more votes than the Democratic candidate just ONCE.
Trickle down economics, tax cuts all that is simply bullsh*t which only helps the 1%.
Thus, the GOP uses the LIE of 'voter fraud', which exists on the level of about ten bad votes per US election, as a lie to cover their REAL intent with voter ID laws, to REDUCE the Democratic voter turnout.
A new study from researchers Zoltan Hajnal, Nazita Lajevardi, and Lindsay Nielson at the University of California San Diego is one of the first to analyze certified votes across all states after the implementation of voter laws in multiple elections, and it found just that kind of racially discriminatory impact.
Specifically, they found “that strict photo identification laws have a differentially negative impact on the turnout of Hispanics, Blacks, and mixed-race Americans in primaries and general elections.”
"Every election, roughly half the population votes Democrat, the other half votes Republican. I understand why Republicans get 1% of the vote . . . the richest 1%. That other 49% (of Americans) someone will just have to explain to me. The facts about what the Republicans have done to the Middle Class are beyond reasonable doubt. And yet their base refuses to see it. The moneyed elite of America are dragging a bag filled with your future down the steps and your reaction is, "Hold on there, that looks heavy, let me give you a hand getting that into your trunk.""
