One part of 2020 that has thusfar gone Underdiscussed is the Puerto Rico House of Representatives Generic Ballot, However, as one of two types of statewide Vote that the PPD Won(the other being the Mayoral Generic Ballot) Taking a look at the House of Representatives Popular vote by Distrito Senatorial can provide some insights as too what the House GE Looked like.
What wee see from this is that the PPD's House coalition looks more like the Fortuño 2012 coalition than the Pierluisi Coalition.
This can be seen through their Popular Vote win in the Arecibo Senate District (which Fortuño Carried but Pierluisi Did Not), and Loss in the Humacau/Carolina Senate Districts, where the opposite occured.
I'll note however that the House PNP did Carry the San Juan SD, which was only carried by Pierluisi 2020, and not Fortuño 2012. But this was due too the 19% Landslide the PNP had in Distrito 1(Viejo San Juan/Isla Grande*) & their comfortable win in Distrito 5 (Southern San Juan**, Aguas Buenas, & Southern Guaynabo)
*In what was the Old Municipio of San Juan
**In what was the Old Municipio of Río Piedras
I'd Like to hilight the Reason that the PNP were able to carry the Arecibo Senate District, and that was due to José (Memo) González's 10.1% win over his PPD Chalenger, where all the other districts failed to crack 3% for either the PPD & the PNP.
I'd also like too add that Pierluisi only Carried this district by 2.5% respectively, Contributing all three of them loosing the Arecibo Senate District by 0.28%. (I'll also note both PNP senate candidates combined only carried the district by 2.6% which as mentioned before was pivotal in their loss)
In addition too showing the effect of ticket splitting in Puerto Rico, and presenting the Diference between Pedro Pierluisi and the PNP's Legislative wing, I'd be hard press too miss the one district where the party that had a Majority of the vote got a Minority of Seats, Carolina.
This split mainly occured because of the fact that the 3 Races the PNP won were by relatively close margins(between 1-5%), but the PPD incumbents Attained strong margins(5-9%), thereby causing the split(I should note that Distrito 38 in the Carolina Districts, was the PNP's only district pickup in 2020).
