I'm not totally disagreeing with your point, but I wonder how you feel when the left goes on and on about voter suppression without offering up proof? Does that not also effect how the public views the validity of elections? It cuts both ways, not just one. Neither side is innocent so let's not pretend they are.
In cases where no proof of the voter suppression is provided, it is irresponsible and reckless. Now, having said that, when I'm watching "Rachel Maddow", she goes into very specific details of where the suppression is being done, how it's being done, who is impacted and who is responsible.
Three specific recent cases cited on Maddow's show include
(1) the suppression of Native American voters in North Dakota - who were required to supply a voter ID with a physical address when it is well known that Native American residents primarily use P.O. boxes and tribal identification on their personal ID's which doesn't list a street address. Native Americans are also over represented among the homeless population. This silly law of requiring a street address on the ID is an obvious attempt to suppress their vote - which is primarily to the Democratic side.
(2) A second such example cited recently was done by Kris Kobach, the Kansas Secretary of State, who was guilty of a blatant attempt to undercut voter turnout in the western Kansas county of Ford (Dodge City). Due to the closing of polling locations in the mostly Democratic leaning county, there was not actually a polling location anywhere within the county itself. If you are a resident of Ford County, Kansas and wanted to vote, you had to drive to the expo center outside of town. It's even a new site because construction made the previous site inaccessible. Even more inconvenient for voters in Ford county is that there are no public transportation services to this expo center. In fact, the nearest bus stop is nearly a mile away... and at times freight trains block traffic to this center, further slowing down access to the polls. However, all of this was not enough to keep Kobach from losing his race for Kansas Governor anyway. Finally, we have
(3) the state of Georgia and the so-called "exact match" law. In yet another case where a Republican Secretary of State was also running for Governor but refused to recuse himself from his job as supervisor of elections, Brian Kemp was very eager to enforce the state's law stating that a voter's registration is incomplete if information on that form doesn't precisely match records kept by Georgia's Department of Driver Services or the Social Security Administration. If so much as a hyphen is left out of a name, the application can be placed in pending status with the applicant notified by mail (though often not) that additional documentation may be required. As a result of this law, the registrations of 53,000 voters were placed on hold, largely of African-Americans (of course). On November 2, a federal judge issued a ruling removing the "exact match" barrier, easing the ability of the voters impacted by it to vote on November 6.
I'm sorry but when it comes to allegations of voter suppression, the examples are normally cited by liberals because they are very frequent in nature and easy to describe. You don't have a leg to stand on here... Donald Trump has never gone into such detail when alleging voter fraud on the part of Democrats. NEVER.
