For example, every state that even proposed election ID laws was subject to Voting Rights Act actions, even if they werent included as being subject to Section 5 preclearance before the finding of the Section 4 formula as unconstitutional.

The unmitigated war on the hydrocarbon industry

The massive expansion of Title IX actions in universities, aided and promoted by the DOJ

The unfettered war for unions by the NLRB, including provisions for "ambush elections", up until the voiding of the decisions as being made by an unconstitutional voting bloc created by a "lets call a ham sandwich a recess to make a recess appointment."

The use of the IRS to shut down political groups, and using the IRS to circumvent the Citizens United ruling.

The use of massively expanded definitions in the banking industry in attempts to kill off gun businesses, and the same in the efforts to kill off payday loan businesses.

Obama yielded executive power as a massive club for the progressives in many cases, these cases almost always being yielded to provide results that were more widely supported by progressive stances.

The rewriting of immigration law by issuing not an executive order, but executive 'guidelines' that not only implicitly used the the executive power of prosecutorial discretion to end immigration actions for large swaths of illegal aliens, but also introduced 'guidelines' for the issuance of work permits to the same groups, the guidelines for the work permits being actually contrary to US Law.
