OK. Lets look at a few issues.
Gerrymandering. I dont need to post evidence of the GOP. The Democrats, however, are guilty of it as well.
Take Maryland for example.
Electing POTUS. Both parties formally control the process. Each party elects its electors. Parties dont necessarily elect electors in a non-partisan way, but rather elect electors who will carry the party line.
Supporting the two party system. Despite the public's mistrust in general of the two party system, both parties discourage support for third part or independent candidates. They both claim they are wasted votes, and will steal votes from their respective party. Evidence of this is party debates. Only one person has participated in debates that wasnt either Democrat or GOP...Ross Perot in 1992. In 2000, the CPD enacted rules that a candidate must have at least 15% of national support in order to participate. Pretty fair, right?
In most states, both parties control primary elections by requiring voters to use a single ballot for multiple races. In many states, you must register as a Democrat or Republican to vote in POTUS elections.This creates a closed primary. DNC chair Debbie Shultz said “I believe that the party’s nominee should be chosen — this is Debbie Wasserman Schultz’s opinion — that the party’s nominee should be chosen by members of the party,” Yeah. Thats fair.
Both parties receive substantial financial support from Wall Street.
Both parties continue to support significant PAC donations from lobbyists in elections
Members of congress, no matter the party, dont represent those who they are supposed to represent, as most are wealthy and in the top .5%.
Both parties have been involved in scandals involving the solicitation of of foreign money. The DNC in the 90's, the Clinton campaign was fined for soliciting and receiving millions in donations from China, Korea, and Venezuela.. Likewise, the GOP was scrutinized for for setting up a loan in Hong Kong that was allegedly used to funnel money to the GOP. And Trump has been accused of receiving foreign funds for his campaign.
Both parties equally contribute to gridlock and obstructionism in Washington.
Both parties use negative ad campaigns in elections.
Both parties have supported corporate bailouts.
Both parties have engaged in favors to political supporters. Most notedly the DNC with the now bankrupt Solyndra, and the GOP with Halliburton. Amongst others.
Both parties have engaged in questionable POTUS pardons.
Both parties' constituents are pretty sick and tired of partisan politics.
Both parties are responsible for the growth of the federal deficit and debt.
Both parties are responsible for the trade deficit.
Both parties have been accused of violating Americans rights. Bush, with his wiretapping laws under the Patriot Act (ruled unconstitutional) and in 2015 the collections of bulk call data supported by Obama.
Both parties administrations have deployed American troops without a formal declaration of war.
Both parties have similar beliefs in free trade. Neither protectionist or unconditional free trade.
Neither party supports a single payer position for health care.
Shall I go on?
